A Resource and Task Scheduling Based Multi-Objective Optimization Model and Algorithms in Elastic Optical Networks

open access: yesSensors, 2022
The elastic optical network (EON) adopting virtual network function (VNF) is a new type of network, in which the routing, spectrum, and data center allocation are key and challenging problems, and solving these three problems simultaneously can not only ...

Traffic-Driven Spectrum Allocation in Heterogeneous Networks [PDF]

open access: yes, 2015
Next generation cellular networks will be heterogeneous with dense deployment of small cells in order to deliver high data rate per unit area. Traffic variations are more pronounced in a small cell, which in turn lead to more dynamic interference to ...

A Welfare Analysis of Spectrum Allocation Policies [PDF]

open access: yesSSRN Electronic Journal, 2008
Economic analysis of spectrum policy focuses on government revenues derived via competitive bidding for licenses. Auctions generating high bids are identified as “successful” and those with lower receipts as “fiascoes.” Yet spectrum policies that create rents impose social costs.

Traffic Driven Resource Allocation in Heterogenous Wireless Networks

open access: yes, 2014
Most work on wireless network resource allocation use physical layer performance such as sum rate and outage probability as the figure of merit. These metrics may not reflect the true user QoS in future heterogenous networks (HetNets) with many small ...
